A tank contains 60 kg of salt and 1000 L of water. Pure waterenters a tank at the rate 12 L/min. The solution is mixed anddrains from the tank at the rate 6 L/min.
(a) What is the amount of salt in the tank initially?
amount =Â Â (kg)
(b) Find the amount of salt in the tank after 3 hours.
amount =Â Â Â (kg)
(c) Find the concentration of salt in the solution in the tank astime approaches infinity. (Assume your tank is large enough to holdall the solution.)
concentration =Â Â Â (kg/L)
